sigtige og har Integumenterne paa langt nser lkke saa stserkt 
chitiniserede som kos fuldvoxue Dyr. Ogsaa synes Glang- 
fpdderne forholdsvis noget kortere. Hvad del* imidlertid 
ismr mini a'l'ko r dem, er Beskaftenheden af Saxlenuneine. 
Disse er nemlig forholdsvis stprre end hos de voxne In di- 
vider og har Endepartiet udviklet til en fuldstauulig Chela, 
med vel udprsegede, skjondt korte, kloformige Fingre (se Fig. 
2 1), hvorved de faar en vis Lighed med sannne hos Slsegten 
Phoxich ilddium . Folerne (Fig. 2 m, p) hestaar kun at 6 
Led, idet de 3 yderste endnn ikke er sondrode fra hi nan den, 
og de falske Fodder (ibid. 5) danner kun en ganske kort 
og sinipel, hageformigt omboiet Stamme, i hvis Indre dog 
en begyndende Leddeling lader sig paavise. 
Forekomst. Jeg har af denne Art havt Anledning 
til at undersoge 2 fuldvoxne Exemplarer, Han og Hun, og 
et Par enduu ikke fuldt udviklede Individer. De toges 
alle, ved Christianssund, paa 20—30 F. D. mellem Alger 
og Bryozoer. 
Udbredning. Arten er foruden ved Norges Vestkyst 
hidtil med Sikkerhed kun observeret ved de britiske 0er 
af Hodge. 
Fain. 6. Eurycydidse. 
Legemet fuldstsendig segmenteret ; ogsaa Halesegmentet 
tydeligt afgnendset. Saxlemmerne mere eller mindre rudi- 
mentsere. Haanden sserdeles liden og ufuldkommen cheliform 
hos de voxne Dyr. Foie me stasrkt forkengede, zigzag- 
formigt boiede, 10-ledede, de 2 forste Led meget korte. 
Falske Fodder tilstede hos begge Kjon, 10-ledede og for- 
synede med tydelig Endeklo. Fodderne uden Bikloer. 
Snabelen bevregligt indleddet til et eylindriskt Skaft og 
mere eller mindre boiet iud under Legemet. 
BemEerkninger. Denne Familie viser vistnok enkelte 
Characterer tilfselles med foregaaende, men synes mig dog 
at burde kunne hmvdes, da Here distincte Skegter ladei 
sig naturligt gruppere under sanune. Det mest freni- 
trmdende Tr;ek ved de herhen horende Former er utvivl- 
somt Snabelen s eiendommelige Udvikling og anomale Boi- 
ning ind under Legemet, hvortil endnn kommei en Del 
andre Characterer, saasom Halesegmentcts skarpe Begrsends- 
ning fra sidste Kropssegment, Folernes stserke Udvikling 
og Bygningen af de falske Fodder. Foruden de 2 neden- 
for neermere characteriserede Skegter borer herhen SI.

and their integuments are not nearly so strongly chitinized 
as in the full-grown animal. The ambulatory legs, also, 
appear to be, relatively, somewhat shorter. That which, 
however, especially distinguishes them is the nature ot 
the chelifori. These are, relatively, considerably larger 
than in the adult individuals, and have the terminal part 
developed to a perfect chela with well marked, although 
short, claw-shaped fingers (see fig. 2 1), by which they 
acquire a certain resemblance to those limbs in the genus 
Phoxichilidimn. The palpi (fig. 2 m, p) consist of only 6 
joints, as the 3 outermost ones are not yet separated from 
each other, and the false legs (ibid. 5) form only a quite 
short and plain, unciform incurvate stem, in whose interior, 
however, a rudimentary articulation may be detected. 
Occurrence. I have had the opportunity ol inves- 
tigating 2 fully grown specimens of this species, male and 
female, and a couple of not yet fully developed individuals. 
They were all taken at Christianssund, at a depth of 
20 — 30 fathoms, among Algae and Bryozoa. 
Distribution. Besides on the West Coast of Nor- 
way, the species has, hitherto, only been observed, with 
certainty, off the British Islands by Hodge. 
Fam. 6. Eurycididae. 
Body perfectly segmented; caudal segment also dis- 
tinctly demarcated. Chelifori more or less rudimentary, 
the hand particularly small and imperfectly cheliform in 
the adult animal. Palpi greatly elongated, curved in zig- 
zag form, 10-jointed, the 2 first joints very short. False 
legs present in both sexes, 10-jointed, and furnished with 
distinct terminal claw. Legs without auxiliary claws. Pro- 
boscis movably articulated to a cylindrical scape, and more 
or less curved in under the body. 
Remarks. This family certainly exhibits some charac- 
ters common also to the preceding one, but yet it appears 
to me, that it ought to be maintained separate, as several 
distinct genera may be naturally grouped within it. The 
most prominent feature in the forms pertaining to it is, 
undoubtedly, the peculiar development of the proboscis 
and its anomalous folding in under the body, to which 
are added several other characters, such as the distinct 
demarcation of the caudal segment from the last segment 
of the trunk, the great development of the palpi and the 
structure of the false legs. Besides the 2 genera more 
particularly characterized in the sequel, the genus Parana, 
Dohrn belongs to it, and probably also the genera Par- 
azetes Slater, Aldnous, Costa, and Nymphopsis, Schimke- 
witsch.
